A large amount of welding slag that splashes can remain in rifle head after the welding of robot welder, if can not effectively clear up, must influence welding quality for the loss of consumptive materials such as spray tube and conductive nozzle has invisibly increased manufacturing cost, influences going on smoothly of whole production beat simultaneously, extravagant a large amount of production time, reduction automated production efficiency.
The existing scraper is in a rigid straight cylinder shape, and adopts a side opening to remove chips, and the other parts are closed spaces. Most of consumables such as spray pipes and conductive nozzles in the market are conical, the straight barrel-shaped scraper can only clean welding slag in a very limited area, and a large amount of welding slag still remains on the conical surfaces of the consumables such as the spray pipes and the conductive nozzles. In actual use, due to the influence of various factors, the centering and debugging difficulty of the rigid scraper center and the welding gun center is high, so that the phenomenon that consumables such as a spray pipe, a conductive nozzle and the like are scraped frequently occurs. When the gun is cleaned, the welding slag is accumulated in the closed space and cannot be discharged under the influence of the centrifugal force of the high-speed rotation of the scraper and the gravity of the welding slag.
Disclosure of Invention
In order to solve the technical problem, the invention provides a flexible scraper for cleaning a robot welding gun. The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a flexible scraper for cleaning a robot welding gun comprises a scraper holder, wherein the scraper holder is connected with a flexible scraper which extends into the welding gun through plastic deformation to clean welding slag, a cleaning cutting edge for scraping the welding slag is arranged at the front end of the flexible scraper, and a chip removal gap for discharging the welding slag is arranged on the flexible scraper;
the robot drives the welder motion, makes flexible scraper get into in the welder cavity, rotates through blade holder self simultaneously, drives flexible scraper and rotates, makes the clearance blade strike off the welding slag to discharge the welding slag through the chip removal clearance.
The flexible scraper is a right-handed spiral alloy spring extending along the axis direction of the cutter holder, and the chip removal gap is an interval between two adjacent circles of springs.
The helix angle of the alloy spring is 5 to 9 degrees.
One end of the flexible scraper, which is far away from the cleaning cutting edge, is provided with a tightening end which is connected with the cutter holder to fix the flexible scraper.
And the cutter holder is provided with a thread matched with the tightening end.
